And the color temperature and CRI, tell you what the
light will look like. The three on the right above are
2700K 90CRI, which means roughly "almost the same as
an incandescent". A warm-ish light, suitable for reading.
The 5000K 85CRI bulbs I bought, the floods, those
are dreadful, and I can't use those for anything.
And I don't really understand what goes on with those,
as the light is "white", but it's also "bleh" and
indescribable in any meaningful way. They don't
look bluish, as the 5000K would hint, there's no
sign of blue the way some bulbs at that color
temperature look. But the light is just awful
and you just want to turn it off. It's "poke in the eye"
awful. I'd rather light the room with a magnesium flare.

5000K means more blue & less red. It still looks white, just nasty.

People in cool countries mostly like warm white, which is of course lower CCT.

White LEDs are cool white by nature, warm white ones have pale yellow or less often orange colour over them.
